Description

  The present invention relates to a chair type massage machine provided with an ottoman.

  Conventionally, a seat portion, a support portion that is pivotably connected up and down in front of the seat portion, an ottoman that is slidably supported by the support portion, and a lift that pivots the ottoman up and down via the support portion A chair-type massage machine is known that includes a mechanism and a lock mechanism that fixes an ottoman to a support portion with an arbitrary slide amount (see, for example, Patent Document 1). In this case, the posture and position of the ottoman can be freely changed according to the body shape and preference of the user, and a high massage effect can be obtained.

  Here, in the chair type massage machine, when the ottoman is rotated downward, unless the user releases the lock and returns the ottoman to the original slide position, the ottoman contacts the floor surface during the rotation. Will stop.

Therefore, conventionally, means for remotely operating the lock mechanism by wire operation has been used as means for releasing the fixation of the ottoman by the lock mechanism. However, when the lock mechanism is operated using the wire, the wire extending from the lock mechanism side needs to be largely routed to the vicinity of the lever on the seat portion. As a result, there arises a problem that the lever operating force required when releasing the lock mechanism is increased and a problem that it is difficult to quickly release the lock mechanism after the lever is operated.

  The chair type massage machine of the present invention does not require a large operating force to release the ottoman, and has the effect that the fixation can be released quickly and reliably.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In FIG. 2, the whole chair type massage machine of an example in embodiment of this invention is shown. The chair type massage machine of this example includes a seat 2 for a user to sit on, a backrest 3 for a user sitting on the seat 2 to lean his back, and a seat 2 The massager body 1 is mainly composed of the elbow rests 4 provided on the left and right sides of the seat 2 so that the user who is in the seated state puts his arm, and the user who is seated in the seat 2 The ottoman 6 for holding the lower part of the knee is connected to be slidable up and down and slidable. Furthermore, the operation device 5 is connected to the massage machine main body 1 through a cord 5a. In addition, each direction, such as up and down, left and right, and front and rear, used in the text is based on a direction viewed from the side of the user who is sitting on the seat 2.

  The ottoman 6 is formed with a pair of left and right groove portions 6a into which the entire lower knee portion of the legs of the user is fitted. As shown in FIG. 2 and FIG. 3, an airbag 7 is disposed on the inner wall of each concave groove 6a to hold the calf portion of the user from both sides. Moreover, the airbag 8 which clamps a user's sole, a foot tip, and an ankle part is distribute | arranged to the inner side wall at the front end side of the recessed groove part 6a. In this example, treatment means for holding and massaging the legs of the user by the airbags 7 and 8 is formed.

  The ottoman 6 is pivotable in the vertical direction with respect to the massage machine main body 1 through a support portion 9 as shown in FIGS. 3 and 4 and in a predetermined sliding direction close to and away from the seat portion 2. It is structured to be slidably connected toward the head. The support portion 9 is connected to the massage machine main body 1 so as to be rotatable in the vertical direction at a position in front of the seat portion 2, and connects and supports the ottoman 6 so as to advance and retreat in a predetermined slide direction.

  In the slide mechanism for slidably connecting the ottoman 6 and the support portion 9, the slide member 10 fixed to the center portion in the left-right direction of the ottoman 6 and the slide support member 30 fixed to the support portion 9 side slide. It is formed by fitting freely.

  Further, a pair of left and right coiled tension springs 11 are interposed between the support portion 9 and the ottoman 6 as urging means for urging the ottoman 6 in a direction approaching the seat portion 2 side. ing.

  The lift mechanism 12 that controls the posture of the ottoman 6 by rotating the support portion 9 up and down is a support means that can be expanded and contracted in the front-rear direction between the support portion 9 and the massage machine body 1 (FIG. 5). reference). As shown in FIG. 6, the lift mechanism 12 is fixed to the worm shaft 13 whose one end is rotatably connected to the massage machine body 1, a motor 14 meshing with the worm shaft 13, and the motor 14. A main body is formed by a columnar drive body 15 that is integrated with the motor 14 and driven to advance and retreat along the worm shaft 13 and a cylindrical coupling body 16 fitted from the front end side of the drive body 15. .

  Here, as shown in FIG. 5, when the motor 14 is rotated and the driving body 15 moves in the extending direction of the lift mechanism 12 (i.e., the front), the connecting body 16 is also pushed by this and moves integrally in the extending direction, The support part 9 rotatably connected to the connecting body 16 and the ottoman 6 supported on the support part 9 are rotated upward. Further, when the motor 14 is rotated in the reverse direction and the driving body 15 moves in the contraction direction (that is, rearward) of the lift mechanism 12, the connecting body 16 that receives the weight of the ottoman 6 and the support portion 9 follows the driving body 15. The support part 9 that moves in the contraction direction and is rotatably connected to the connecting body 16 and the ottoman 6 supported on the support part 9 are rotated downward.

In this example, as a lock mechanism 20 for fixing the ottoman 6 to the support portion 9 with an arbitrary slide amount, as shown in FIG. a locking member 18 and the position-decided Me member 17 is disposed on the supporting portion 9 side so as to be engaged with any of the engagement point 17a of the positioning member 17 having a positioning of the locking member 18 And a solenoid 19 for switching on / off of the locking with the member 17.

  The positioning member 17 is a rack-like member that is formed in parallel with the slide member 10, that is, in a sliding direction, and is formed by arranging a number of locked portions 17 a that are groove-shaped along the sliding direction. The locking member 18 is a member installed on the support portion 9 so as to be rotatable about the shaft 18a.

  The solenoid 19 surrounds the plunger 22, a magnetic metal case 21 serving as a yoke, a plunger 22 disposed in the case 21 so that the tip protrudes and the protruding amount can be changed within a predetermined range. The coil 23 arranged in the case 21 and the spring 24 arranged in the case 21 so as to urge the plunger 22 in the protruding direction constitute a main body. When the energization of the coil 23 is turned off, the plunger 22 largely protrudes due to the urging force of the spring 24, and when the energization of the coil 23 is turned on, the plunger 22 moves backward against the urging force of the spring 24 by the magnetic force. Yes.

  The energization control to the coil 23 of the solenoid 19 is performed by a control unit 25 comprising a microcomputer. That is, the solenoid 19 can switch the magnitude of the protruding amount of the plunger 22 by energization control from the control unit 25, and by engaging the locking member 18 with the tip of the plunger 22, The posture of the locking member 18 can be switched in conjunction with the switching of the protruding amount of the plunger 22.

  The locking member 18 is provided with a locking piece 18b, and when the protruding amount of the plunger 22 is large as shown in FIG. 1A, the locking member 18 has its locking piece 18b. Is in a position that can be locked in the locked portion 17a of the positioning member 17, and when the protruding amount of the plunger 22 is small as shown in FIG. 18b becomes a posture which cannot be locked in the locked portion 17a of the positioning member 17.

  In addition to energization control to the solenoid 19 (that is, on / off control for sliding fixation of the ottoman 6), the control unit 25 controls driving of the treatment means provided on the massage machine body 1 side and the ottoman 6 side, and the lift mechanism 12. The drive control is performed. The operation unit 5 includes various operation switches 26 for the user to turn on / off the power, drive each treatment means, turn on / off the ottoman 6 and fix the backrest 3 and the ottoman 6. The control is performed based on a signal input from the operation switch 26 to the control unit 25 (see FIG. 9).

  Here, in this example, separately from the operation switch 26 on the operation device 5, an operation switch 27 for allowing the user to operate the lock mechanism 20 to release the ottoman 6 from being slid is provided on the elbow. They are arranged on the upper surface of the placing portion 4 and in the recessed groove portion 6a of the ottoman 6, respectively. The operation switch 27 on the ottoman 6 side is arranged on the inner bottom surface of the recessed groove portion 6a of the ottoman 6 as shown in FIG. 2 (c), and the lower leg portion that the user holds in the recessed groove portion 6a. The lower surface can be contacted. As a result, the user can perform the release operation with the ottoman 6 holding the legs. The operation switch 27 may be disposed at other locations on the ottoman 6, for example, on the inner surface of the recessed groove 6 a where the lateral surface of the lower leg portion of the user can contact, or the sole portion is in contact. It may be a possible place or a place where the side portion of the foot can touch.

  It should be noted that the operation switches 26 and 27 for turning on and off the ottoman 6 to be slidably fixed may be at least one of the elbow rest portion 4, the operation device 5, and the ottoman 6.

  In the control unit 25, the solenoid 19 is driven and controlled in accordance with the posture (that is, the rotation angle) of the ottoman 6 by the drive control of the lift mechanism 12 regardless of the commands from the operation switches 26 and 27. The on / off of the lock mechanism 20 is forcibly controlled. This is to avoid the ottoman 6 coming into contact with the floor surface 50.

  The on / off control of the lock mechanism 20 here is specifically as follows. That is, in the control unit 25 of this example, when the ottoman 6 is rotated upward by extending the lift mechanism 12 as shown in FIG. 7, the ottoman 6 is rotated upward from a predetermined posture. Regardless of commands from the operation switches 26 and 27, the solenoid 19 is driven and controlled so that the locking of the locking member 18 of the lock mechanism 20 and the positioning member 17 is turned on (that is, the solenoid 19 is energized). Is off).

  The predetermined posture is a posture at a rotation angle α at which the ottoman 6 comes into contact with the floor surface 50 when the ottoman 6 is most slid in a direction away from the seat portion 2. Here, the rotation angle α is based on the initial storage posture in which the tip of the ottoman 6 is directed downward.

  This prevents the ottoman 6 that has been slid inadvertently from coming into contact with the floor surface 50 and causing damage during the upward rotation of the ottoman 6 from the storage position.

  Further, in the control unit 25 of this example, when the lift mechanism 12 is contracted and the ottoman 6 is rotated downward as shown in FIG. 8, the ottoman 6 is rotated downward from the predetermined posture. For example, the solenoid 19 is driven and controlled so that the locking of the locking member 18 of the lock mechanism 20 and the positioning member 17 is turned off regardless of the commands from the operation switches 26 and 27 (that is, the energization of the solenoid 19). Is turned on).

  As a result, even when the ottoman 6 is rotated downward while being in a sliding state, the ottoman 6 is released from being fixed before the ottoman 6 comes into contact with the floor surface 50 and is damaged. To prevent damage due to contact with the.

  The posture of the ottoman 6 is detected by using a sensor 28 (see FIG. 6) arranged on the drive body 15 side of the lift mechanism 12. The sensor 28 detects the position of the driving body 15 in the expansion / contraction direction with respect to the worm shaft 13 by reading the slit of the position detection member 29 fixed to the worm shaft 13. Is read to determine the posture of the ottoman 6.

  Moreover, you may provide so that the above-mentioned on-off control of the locking mechanism 20 may be performed based on the operation program set beforehand, without relying on the said sensor 28. FIG.

  Note that the forced on / off control of the lock mechanism 20 by the control unit 25 here is not limited to the above, and for example, the ottoman 6 rotates regardless of whether the rotation direction is upward or downward. At that time, the solenoid 19 may be driven and controlled so that the locking of the positioning member 17 and the locking member 18 of the lock mechanism 20 is automatically turned off. This also prevents the ottoman 6 from coming into contact with the floor surface 50 and causing damage.

  Further, in the control unit 25 of this example, when the energization to the solenoid 19 is turned on so that the locking of the positioning member 17 and the locking member 18 of the lock mechanism 20 is turned off, the airbag 7 and 8 are provided to stop the leg treatment means.

  Therefore, in the chair type massage machine of this example, since the on / off of the ottoman 6 can be controlled by using the solenoid 19 that is quickly driven by an electric signal, a wire operation is performed to release the ottoman 6 from being fixed. Such a large operating force is not required. Moreover, it is possible to quickly and reliably release the fixation. In addition, the control unit 25 forcibly controls the solenoid 19 regardless of the operation of the user, and is provided so that the ottoman 6 does not come into contact with the floor 50 during the rotation. The surface 50 is reliably prevented from colliding and causing damage.
